JavaScript - 替换字符串中的方括号 [英] JavaScript - replace square brackets in a string

问题描述

我有一个简单的字符串并试图将 [~sample] 转换为 @sample.例如:

I have a simple string and trying to convert [~sample] to @sample. For example:

var string = 'Completely engineer client-based strategic [~theme] areas before cross [~media] technology';
string.replace('[~', '@');

我已经尝试了上述解决方案，但它只转换了第一个，并且无法删除 ].

I have tried above solution but it only convert the first one and the ] can not be removed.

现在我学会了如何使用/g

now I learnt how to use /g

推荐答案

这个问题比简单地嵌套 .replace [@ 和 ] 要复杂一些

The issue is a bit more complicated than simply nesting .replace [@ and ]

var string = 'Strategic [~theme] areas with cross [~media] technology [this is fine] ok?';

document.body.innerHTML = string.replace(/\[~([^\]]+)\]/g, '@$1');

([^\]]+) 确保捕获任何不是 ] 但由 [~ 分隔的字符和 ]，这在任何情况下都是一个更好的解决方案，可以防止像 [别惹我] 之类的文本被......搞砸.

The ([^\]]+) makes sure to capture any character that is not an ] but is delimited by [~ and ], which is a better solution in any case preventing text like [don't mess with me] to be... messed.

RegExp 在这里
